What Peter Attia recommended
In transcript order-
Attia is highly optimistic that adoptive cell therapies using TIL and engineered T cells will be able to eradicate most solid organ metastatic cancers within ~10 years.
“designer-based immunotherapies to eradicate most solid organ metastatic cancers
CaveatsCurrently expensive (~$300k); may not be insurance-covered initiallyCertaintyspeculativestrong endorsement -
In a protocol
Attia advocates aggressive colon cancer screening via colonoscopy, starting around age 40 with no family history, and repeating every 1-3 years rather than every 5-10.
“nobody should ever die from colon cancer
DosageFirst at age 40; repeat every 1-3 yearsCaveatsCosts ~$2,000 out of pocket; small sedation and perforation riskCertaintyexplicitstrong endorsement -
In a protocol
Attia recommends combining upper endoscopy with colonoscopy to screen the esophagus and stomach for cancer.
“you basically get for free the esophagus and stomach
Certaintyexplicitrecommendation -
In a protocol
Attia prefers measuring ApoB over LDL cholesterol because it captures total atherogenic lipoprotein concentration in one number.
“we have one single number that captures the total concentration of ApoB
DosageAim to keep ApoB below 60 mg/dL (~5th percentile)CaveatsMany US physicians don't routinely order ApoB; patient may need to requestCertaintyexplicitstrong endorsement -
In a protocol
Attia personally combines a PCSK9 inhibitor with a statin to dramatically lower ApoB.
“I take a PCSK9 inhibitor and I take a statin
Certaintypersonal onlypersonal use -
In a protocol Alternative
Preferred starting statin alongside rosuvastatin for lipid lowering.
“I like to start with Razuvastatin or Pravastatin
Certaintyexplicitrecommendation -
In a protocol
Attia's preferred starting statin for ApoB lowering, along with pravastatin.
“I like to start with Razuvastatin or Pravastatin
Caveats~5% of patients have intractable muscle soreness with statinsCertaintyexplicitrecommendation -
In a protocol Alternative
Second-line statin choice after rosuvastatin/pravastatin if tolerance is an issue.
“move to Pitavastatin or Livalo
Certaintyexplicitrecommendation -
In a protocol Alternative
Used in hypersynthesizers who can't tolerate statins for lipid lowering.
“If they're a hypersynthesizer but can't respond to statins, we use mapendoic acid
Certaintyexplicitrecommendation -
Attia is increasingly interested in testing modifier genes (TOMM40 haplotypes, mitochondrial haplotypes, Klotho VS variant) that modulate APOE4 Alzheimer's risk.
“actually seems to erase all of the downside of ApoE4
CaveatsCurrently labor-intensive and expensive (>$20k whole genome sequencing); takes monthsCertaintyhedgedrecommendation -
Attia is now skeptical that TRF offers benefit beyond caloric restriction and warns it can cause lean mass loss, especially with one-meal-a-day patterns.
“most of the benefit of time-restricted feeding is accrued through caloric restriction
CaveatsCan work for very overweight individuals with lean mass to spareCertaintyexplicitmild caution -
Attia recommends VO2 max testing as a key metric of cardiorespiratory fitness and longevity.
Certaintyexplicitrecommendation -
Attia argues most people under-consume protein; the RDA is too low and intake closer to 1 g per pound of body weight is more appropriate for thriving.
“closer to two grams per kilogram or about a gram per pound of body weight
Dosage~2 g/kg body weight (~1 g/lb); toxicity concern not until 3-4 g/kgCaveatsExcessive protein (3-4+ g/kg) may stress kidneysCertaintyexplicitstrong endorsement -
Attia emphasizes resistance/strength training as critical for healthspan and lifespan, particularly in middle-aged women who often neglect it.
Certaintyexplicitstrong endorsement -
Attia uses farmer's carries (e.g., 70-75 lbs per hand) as supersets to build grip strength.
“doing a farmer's carry in between other workouts
Dosage~70 lbs per hand, supersetted with ski erg intervalsCertaintypersonal onlypersonal use -
Attia uses BFR (Kaatsu) training to maintain muscle while rehabbing from shoulder surgery, using isometric loads with restriction rather than joint stress.
“blood flow restriction with my cats
Certaintypersonal onlypersonal use -
Attia remains highly skeptical that NAD precursors offer phenotypic benefit in normal aging individuals.
“Incredibly uninspiring data so far
CaveatsOpen to being proven wrong with good dataCertaintyexplicitmild caution -
Alternative
Same skepticism applies to NMN — raises NAD but no shown phenotypic benefit in healthy aging.
Certaintyexplicitmild caution -
Attia cautions that psychedelics alone don't produce durable change; they should be paired with serious psychotherapy before and after.
“psychotherapy is probably the most powerful tool
CaveatsMolecule isn't the solution; the deep therapeutic work surrounding it isCertaintyhedgedmild caution -
Attia describes DBT as a powerful, tool-oriented form of psychotherapy.
“amazing type of therapy that's more tool oriented
Certaintyexplicitrecommendation -
Attia is now less worried about blue light per se before bed; he thinks the stimulating content (e.g., Twitter) is the bigger sleep disruptor.
“less concerned with the light from electronics before bed than I used to be
Certaintyhedgedoffhand mention -
Alternative
Attia recommends low-dose trazodone (off-label) as a maintenance sleep medication that preserves sleep architecture, unlike Ambien or benzodiazepines.
“remarkable sleep both in quality duration and lack of interruption
Dosage25-100 mg before bed (off-label)CaveatsDoesn't work for everyone; some have residual morning grogginess; requires prescriptionCertaintyexplicitstrong endorsement -
Attia avoids prescribing benzodiazepines for sleep due to dependency issues.
“we would never prescribe them to anybody because of the dependency issues
Certaintyexplicitstrong warning -
Attia highly recommends Michael Easter's book on the harms of modern over-comfort and how to reintroduce productive discomfort.
“I recommend it highly
Certaintyexplicitstrong endorsement
